Optimal Universal Controllers for Roll Stabilization [PDF]
, 2020 Roll stabilization is an important problem of ship motion control. This problem becomes especially difficult if the same set of actuators (e.g. a single rudder) has to be used for roll stabilization and heading control of the vessel, so that the roll ...

Rudder roll stabilization for ships [PDF]
, 1990 This paper describes the design of an autopilot for rudder roll stabilization for ships. This autopilot uses the rudder not only for course keeping but also for reduction of the roll. The system has a series of properties which make the controller design

Strength Analysis of a Novel High-Pressure Die with Double-Layered Split Structure
Metals, 2018 A novel double-layered split die (DLSD) was designed to have higher pressure-bearing capacity and larger sample cavity volume. In DLSD, the cylinder and first layer supporting ring are split into several blocks.

A High Compressibility Pressure—Sensitive Structure Based on CB@PU Yarn Network
Sensors, 2018 In this work, a piezoresistive sensor structure based on carbon black (CB)@polyurethane (PU) yarn material was developed. Specifically, CB@PU yarn was constructed by the polymer-mediated water-based electrostatic deposition method.

Noncommutative spacetime effect on the slow-roll period of inflation [PDF]
, 2004 We study how the noncommutative spacetime affects on inflation. First we obtain the noncommutative power spectrum of the curvature perturbations produced during inflation in the slow-roll approximation.

The technique of determining the small angular deviations by an electrostatic sensor
St. Petersburg Polytechnical University Journal: Physics and Mathematics, 2022 Some methods for determining small angular deviations have been considered on the example of building objects. The design of an electrostatic cylindrical sensor was put forward, and the use of force action of an electric field was proposed in order to ...

, 2021 <p>During the final months of 2011 the New Zealand government revisited a 50 year old proposal to move the inter-island ferry terminal, currently located in Picton, to a site bordering on both Lake Grassmere and the Clifford Bay coastline. This thesis is based around the design of the new terminal facilities.The primary goal of this research is ...
